Air (or steam or inert gas) is circulated horizontally by turbofans 50 rotated by shaft 67 concentric with the shaft 66 and a bearing 65. The air may be recirculated or exhausted from the dryer or preheated, and the housing is kept at a slight negative pressure. The material is spread evenly over the tray by an adjustable leveller arm 138.

IPC: C07C17/10
Filed: 1962-06-01
Abstract: Unsaturated chlorides of the formula CH2Cl. CR:CH2, where R is a hydrogen atom or an alkyl group, are prepared by the hot chlorination of olefines of the general formula CH3.CR:CH2 by preheating the olefine to a temperature of 250-350 DEG C., mixing it at this temperature with chlorine, and after a period of at most 1 second cooling the products, then separating the said unsaturated chloride formed, and recycling to the initial olefine feed unreacted olefine and saturated chlorinated hydrocarbons formed as by-products and intimately mixing them therewith, the total molar ratio of olefine to chlorine in the reaction mixture being at least 2:1 and the temperature reached by the reactants being 500-550 DEG C. Preferred olefines are propylene and isobutylene. Hydrogen chloride and unreacted olefine may be separated from the other compounds leaving the reaction zone by fractional condensation and the olefine freed from hydrogen chloride before being recycled. In a modification of the process, a part of the unsaturated chloride produced is recycled with or without saturated hydrocarbon dichloride, and a dichlorinated olefine is produced as a by-product.  Examples are given.

Title: Method of producing furfural and organic acids
IPC: C07D307/50
Filed: 1937-08-04
Abstract: Spent wort from the fermentation of wood sugar is heated with hydrochloric or sulphuric acid, and the volatile products evolved are fractionated to recover furfurol, acetaldehyde and its homologues, and acetic acid; the wort may first be concentrated, if desired.  The residual acid liquor (A) contains levulinic acid and other organic acids, and these may be extracted with an organic solvent, e.g. tetrachlorethane, if desired after concentrating the liquid.  The residual acid liquor (A) may alternatively be made alkaline, heated and reacidified, whereby insoluble substances in the liquid are converted into organic acids, mainly levulinic and lactic acids, which are then extracted.  Alternatively, the acids may be recovered in the form of their esters by heating the acid-containing liquids with methyl or ethyl alcohol and extracting the esters with an organic solvent, e.g. benzene or tetrachlorethane.  The furfurol produced as described above may be stabilized by adding a small proportion of ammonia or an aliphatic amine, e.g. triethanolamine, during the distillation or rectification of the furfurol.

Abstract: 834,659. Coating by vapour deposition. MINISTER OF SUPPLY. May 13, 1954 [Feb. 17, 1953; May 5, 1954], Nos. 21509/55 and 21510/55. Divided out of 834,658. Class 82(2) [Also in Group XXXVI] A method of making a photoconductive cell having a layer of a photoconductive lead salt supported on an insulating surface in an evacuated envelope, wherein the layer of the lead salt is deposited by distillation, includes a step for determining the crystal size comprising either heating the supporting surface during deposition or alternatively depositing the layer on to an unheated or cooled supporting surface and subsequently baking the deposited layer in vacuum at a temperature between 250‹C. and 400‹C. Referring to the Figure, a lead salt, e.g. lead selenide or lead telluride, is placed in a side bulb 6 of a double walled vessel which is evacuated through exhaust tube 5. The bulb 6 is heated to distil the lead selenide on to the region 7; oxygen at a pressure of 10<SP>-2</SP> mm. of mercury is admitted, and the lead salt successively distilled to region 8 and thence on to the final supporting surface 4, oxygen being admitted as necessary to maintain the pressure at 10<SP>-2</SP> mm. The temperature of the supporting surface 4 during final deposition is controlled according to the crystal size and hence the wavelength sensitivity characteristic required, the relation between crystal size and wavelength sensitivity being determined beforehand by trial runs. In an alternative method the surface 4 is cooled by liquid air or oxygen during the final deposition and the vessel evacuated; the photoconductive layer is then heated to 250‹C. and allowed to cool, heated again to 300‹C. and allowed to cool, and finally heated to 350‹C. and allowed to cool, the sensitivity of the layer being tested between each baking process. Specification 647,616 is referred to.

Title: Improvements in or relating to tractors

Abstract: 820,064. Tractor power-lift mechanisms. INTERNATIONAL HARVESTER CO. July 8, 1957 [Oct. 5, 1956(2)], No. 21538/57. Class 79(1) In a tractor, implement - attaching and draught control mechanism comprising a draught structure extending forward under the tractor's rear axle for anchorage has a twopoint connection 25-26 for an implement 30, a movable anchorage 22 on the tractor 10 for pivotal connection of its front end 15 to allow the draught structure longitudinal movement in response to draught forces acting on the implement, means additional to the normal hydraulic lifting gear for raising and lowering the draught structure and a mechanism to tr a n s m i t movement from the anchorage 22 to the lifting means so that an increased draught load results in a lifting force being applied to the implement. The anchorage 22 comprises a lever arm which is fixed to a transverse shaft 23 rotating in a bracket 24 on the tractor body 10. A rod 79, Fig. 7, is connected to the arm 22 by an arm 80 that is also secured to the shaft 23 has its front end 78 forked to carry a thrust block 76 mounted on a pin 77 and contacting a cam surface 75. The cam surface 75 forms one edge of a lever arm 74 on a bell-crank structure pivoted to the tractor and having its other arm connected to the raising mechanism arms 43 and 44 through hydraulic gear 60 which acts as a rigid link when inoperative. The bell-crank lever structure can thereby translate a longitudinal displacement of the draught structure 14 into a vertical movement of the implement 30 applied through the arms 43, 44 and the lift links 45 and 46. A manually adjustable bar 91, Fig. 2, sliding vertically in slots (not shown) with positioning stops 95 is attached to the pin 77 so that the initial position of the thrust block 76 on the cam surface 75 may be adjusted to suit a range of conditions. For implements that require only a downward pressure for their operation the bar 91 is pushed down so that the thrust block 76 engages with an extension 98 of the cam surface 75 which is below the pivot of the lever arm 74. Lost motion in the linkages allows limited floating movement of the implement. The draught control can be made inoperative by locking the linkages with a pin at 97. Other details of the mechanisms are as described in Specification 820,603.
